Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 989408, here are decompositions:
- 31 + 989377 = 989408
- 61 + 989347 = 989408
- 67 + 989341 = 989408
- 157 + 989251 = 989408
- 337 + 989071 = 989408
- 349 + 989059 = 989408
- 379 + 989029 = 989408
- 397 + 989011 = 989408
Showing the first eight; more decompositions exist.
